| Hi,
I have encrypted a file with vi(:X). I am the file's owner. I don't
remember the key. Is there anyhow to uncrypt the file ?
Thanks,
Jose Luis

| If there were a way to decrypt the file, then what would be the point of
using crypt in the first place?

Yeah, true, but vim's help files say that the algorithm used to encrypt can
be broken in four hours, so it's not _that_ secure ...

| The enigma encryption algorithm used in crypt(1) (also available in
mcrypt(1)) has known vulnerabilities.
Hint: Crypt Breaker's Workbench
P.S. It's a relatively common mistake for users of vi or ex which are
crypt enabled, to accidentally crypt(1) a file with this built-in
capability. The best defense for this is realizing what has occurred
before exiting the vi session, and writing and confirming that one has
written a file as one desires (either in plain text, or confirming one
knows what the key is and that it works as expected). Unfortunately
the "accidental crypt" mistake typically also includes not knowing the
key.
